'lldy invention relates to hinges, its object being to provide abutt-hinge in which the wear is reduced to a minimum and at the sainetirne the creaking ot the hinge is eliininated, thereby giving anoiseless and easy moving hinge.

lli/ly invention consists in butt-hinge washers interposed between theknuckles in dia rect contact therewith, said washers being formed ofphosphor-bronze or equivalent.

ln the accompanying drawing llligure l is a perspective view of rnyimproved hinge; ltfig. 2 is a vertical section through the joint ot thehinge and Fig. 3 is a view of one ot the washers removed.

lin the drawing the numeral f2 designates a suitable butthinge composedof the leaves 3 and 4. These leaves are provided with 'the knuckles 5and 6 through which the pivctpin 7 passes in the ordlnary manner. 'llhescrew 9 engages the threaded seat in the lowerrnost knuckle of the leali3 in the ordinary manner. Yllhe hinge rnay be tormed et diderent rnetalsbut preterably ot steel,

and inserted between the knuckles are the washers tu.' llhese washersare vlorined ot yahosphoihbronze which is very hard and willreduite thewear to a minimum, and at the saine time such metal has a peculiarproperty which acts in the nature ot a lubricant to reduce the friction.ltlhcn the washers are interposed between the knuckles the hinge werkseasily with slight friction and the consequent wear is reduced to aminirninn. .dit the saine time by the use ot the phosphor-bronze thecrcaking ot the hinge is avoided and without the use ot a lubricant themetal itseli acts in the nature of a lubriis provided.
